Tunnel Kiln Hollow Brick Tunnel Kiln Red Brick Fired Brick Kiln
The Working Principle of Tunnel Kiln
1. Loading materials: The ceramic or brick to be fired is loaded into the kiln at the entrance of the tunnel kiln.
2. Preheating and combustion: The combustion chamber of the kiln ignites the fuel to provide the high temperature required for combustion. The high temperature flue gas produced by combustion flows along the tunnel towards the kiln head under the action of the chimney at the front end of the tunnel kiln or the induced draft fan, and gradually preheats the products entering the kiln.
3. Heat exchange: there are usually multiple partitions in the tunnel kiln to separate the kiln chamber into different areas. There are holes in the partition, so that the flue gas from the kiln through the kiln chamber next to the heating material for heat exchange, improve the efficiency of heat utilization.
4. Sintering and firing: With the increase of temperature, the material gradually reaches the temperature of sintering and firing.
5. Cooling and unloading: When the material is finished firing, the combustion of the kiln will gradually weaken, and the cooling air will enter the kiln. Cold air passes through the kiln chamber to gradually cool the fired ceramic or brick, preventing it from cooling too fast and cracking. Finally, the cooled product is removed from the kiln.
Application of Tunnel Kiln
Tunnel kiln is widely used in the roasting production of ceramic products, and also has applications in the metallurgical industry such as abrasives. Its design not only improves the production efficiency, but also reduces the energy consumption, so that the production cost is effectively controlled. For example, in ceramic production enterprises, secondary roasting tunnel kilns are widely used in the production of various types of ceramic products, and provide strong support for the development of the ceramic industry through scientific management and continuous innovation.
